- 摘要:
- 随着航天器使用寿命的提高,传统滑动式电磁阀设计已不能满足未来发动机控制阀的使用要求。本文介绍一种用于航天器推进系统的长寿命、高可靠、无摩擦簧片式电磁阀的设计和研发。该电磁阀采用簧片式衔铁组件,避免了阀门自身摩擦产生多余物。目前,该设计方案已通过力学环境和热环境试验,完成了一百多万次的工作寿命试验。方案设计通过了试验考核,进入工程实际应用阶段。
- Abstract:
- With the increasing of spacecraft working life, the design of traditional solenoid valves can not meet the requirement of space propulsion system. The design scheme of a long-life, high-credibility, non-friction S-spring valve is introduced in this paper. An S-spring suspended armature style component is adopted in the solenoid to eliminate the redundancy residual caused by sliding friction in the valve. At present, this design scheme has passed mechanics and thermal environment test, and endured a million times of working life cycle. It has entered into engineering application phase.
